Explanation:
Check the attachment for solution
Answer:
1) True: Spring A is stiffer than B (kA > kB). Less work must be expended on spring A if both springs are stretched by the same amount.
2) False: The kinetic energy of an object depends on the direction of the motion involved.
3) True: The work done to raise a box onto a platform does not depend on how fast it is raised.
4) True: The friction force is a non-conservative force.
5) True: The kinetic energy can be negative.
6) False: The kinetic energy does not depend on the reference frame of the observer.
7) False: Work can be done in the absence of motion.
8) False: If the moon revolves around the earth in a perfectly circular orbit, then the earth does do work on the moon.
Answer:
necessary for the growth, development and repair of all body tissues. it's involved in many body functions, including formation of collagen, absorption of iron, the proper functioning of the immune system, wound healing, and the maintenance of cartilage, bones, and teeth.
Explanation:
309.5752 m/s.
First, split the "1385 m" in half, because it takes 2 hours to get that far. So this way, we're turning it into mph (miles per an hour). (If m = miles)
Secondly, turn the mph (miles per an hour) into m/s.
Third, just some calculation, and you're done.
The shape of a particle effect drag.
